NOS exhaust manifold for 350 CI
« on: October 22, 2015, 11:35:57 PM »
I'm searching for the casting number for a set of left and right, exhaust manifold for my LM-1 69 Camaro. I believe that it's the same as the SS350, and some other GM cars, like the Chevelle ?

Anyone have it for same, I can be buyer !

with or without AIR (smog tubes)?
What is your build date?
I have a couple of mid year log style for non-AIR
They will need to be cleaned up- a little rusty

AIR is for Air Injection Reactor (smog system) used on manual trans cars (and all big blocks regardless of transmission)..  but check the CRG pages to be certain (as I don't always remember all the details correctly).. :)

Here's the CRG report link which will explain it all..
http://www.camaros.org/emissions.shtml

The difference in the exhaust manifolds for 350 ci engines is that with manual transmissions, the exhaust manifold will have additional threaded holes into each port of the exhaust manifold to attach the smog tubes.

Correct, and your RH manifold will have the provision for the stove pipe heat shroud which uses the rivets to attach.
